I'm not talking about debug symbols but rather function entry points defined in 
any shared object:

$ nm /lib/libc.so.6
nm: /lib/libc.so.6: no symbols

$ nm -D /lib/libc.so.6 
...
00000000000864b0 W wcstod_l
0000000000083770 T wcstof
000000000008ace0 W wcstof_l
0000000000040810 T wcstoimax
0000000000081e80 T wcstok
00000000000836b0 T wcstol
0000000000083bf0 W wcstol_l
...

All you need is to compile executables with -rdynamic
